Customer Ratings & Reviews

Works great. Keys have decent feel, includes both the keyboard and a track pad, and is wireless via USB. The USB receiver tucks in the battery compartment when not in use. It is small, as seen in the photo next to my full-size Logitech MX Keys keyboard. Fits in my backpack when I need a better keyboard than the ones in my office. Also, it works great with my Raspberry Pi.

My rating is strictly for the product. However I did buy this because I needed a bluetooth keyboard and this was listed a bluetooth keyboard. The keyboard serves its purpose. Its a general use keyboard for designed to give you mobility. Its practical, no bells and whistles. Im giving it 4 stars because: 1 - doesnt come with a manual (which you dont need if you are just connecting to computer), however its a bit complicated if you want to connect to a TV. 2 - As far as connecting to TV, The only piece of paper I got was ikea style instructions on connecting to a TV. Which doesnt appear to be a true connection.. its seems like you are just connecting your laptop to the tv.. and the keyboard connects to the laptop.. From this point of view, it does not seem like you can connect to your smart TV and type into whatever app you are using. The setup is basically connecting your laptop to a TV. 3 - Price point: at this price, in 2024, I think is adequate considering brand name, and practicality. There are probably other brands at same price point, maybe lower, that probably have bluetooth but Im a consumer that likes to use brands im familiar with. I do try other brands but this was an immediate need purchase, theres nothing wrong with the product, it just did not provide the features the website said it did. Im not returning it because im sure i can find use for it, in the immediate future. But I just feel the waste of my time and missed opportunity of making money ( I had bought it for an $800 gig job - which required a bluetooth keyboard as part of the equipment) is more painful than the price. I trust bestbuy and I trust logitech so it was one of those situations where i didnt really read specs and do price comparison.

Great wireless keyboard and touchpad. USB receiver means no hassle pairing with Bluetooth. Perfect if you have more than one computer or device with USB, you just plug the compact receiver into the USB port and away you go. Uses AA batteries so no frequent recharging, batteries can last well over a year depending on use. There's even a great little storage space inside battery compartment to keep small USB receiver when not in use or traveling. Great keyboard at a great price.

So I've had this keyboard for a couple weeks now and I really like it. I’m using it to type this right now. I never heard of a membrane keyboard until seeing this one, and I like it because it doesn’t make a lot of noise when typing and the keys feel kinda… soft? Very smooth and feels good on my fingers, I don’t know how else to describe it lol. The mouse movement is smooth. I had no issues with connecting this to my computer. I thought it was a bluetooth keyboard but turns out it actually comes with a little usb dongle called the Unifying Receiver? Looks like a usb bluetooth adapter, so you need to have an open usb slot to use with your device. The price was reasonable. The "instructions" included in the box were laughable, idk what they were trying to say, but it's easy enough to figure out on your own if you've been using a computer for years. The only problem with it would be with the software, which is why I gave it 4 stars. When I first got the keyboard and began using it I felt the mouse was too slow and the speed didn’t seem to be affected by changing the setting for mouse speed within Windows settings, and also the scroll was inverted, so the only way to fix that was to download Logitech’s companion software that lets you customize some things on the keyboard, which it advertises inside and outside the box. So I downloaded the software and I fixed the inverted scroll issue, but even after raising the mouse speed to maximum it still wasn’t as fast as I wanted so I downloaded the, apparently newer, version of the keyboard software Logitech Options+, and was able to increase the mouse speed. However the most egregious issue was that the scroll was too sensitive, when you scrolled down or up, it would go flying. Changing the mouse scroll setting in Windows or the Logitech+ software to "only scroll 1 line" at a time had no effect. It forced me to have to use the arrow keys to navigate up and down webpages. This has been a known problem for years but Logitech has not made any attempts to fix it. Thanks to Reddit I found a third party app that fixed the problem (X Mouse Button Controls), so if you run into the same problem you can try that. Overall I love the keyboard and its design and would recommend it. The one downside is that I wish it had gestures on the touchpad so that I could swipe left and right to move webpages forward and back. I’m sure there’s probably another third party app that does that out there somewhere though lol.

I originally bought this product to use as a wireless USB keyboard for my Nintendo Switch, it worked well for that but I started using it in my classroom to help with teaching and have found a lot of use for it there. With this product having both a wireless keyboard and mouse, I'm able to teach using content from my computer while away from my desk. I connect it to my computer and I can control the screen, click, type, and change the volume, from anywhere in my classroom.

I have my desktop connected to a 65 inch tv in my living room via hdmi. I use this keyboard in place of a remote. Works perfect.

I have used the different iterations of Logitech's K400 wireless keyboard over the years (K400, K400+ and K400r). At between $15 and $20, they are without a doubt the best way to work with a streaming computer connected to a TV or large display. The keys feel good on the fingers, the track pad is responsive and the batteries last for months of daily use. I only wish that he USB transmitters were harder to lose. bn

I purchased this to use my gaming computer with my flat screen great for using video conferencing. Works really good for home theater where it has some dedicated keys the trackpad is very precise and adjustable as far as sensitivity and scroll the battery life is amazing I use this keyboard everyday I've had it almost 6 months and still have not put a set of batteries in it and I still have 80% I would definitely recommend this to anybody that needs a good all-around wireless keyboard

You cant go wrong with legitech equipment. The touchpad response is really nice. The battery lasts forever it seems. The layout and design makes typing really easy. I use this for my smart TV. It makes life so much easier not having to scan type the screen keyboard with the TV remote which takes all day.

Bought this to control the Raspberry Pi in my game room. Fully compatible with the OS despite not being listed on the box. Track pad feels good to use and the keys are better than you'd expect at the price point, they're pretty good too.

The old K400r was WAY better quality, solid material. This cheap piece of trash, give it a shake and you can just hear all the loose, flimsy bits. The only reason I'm giving it 2 stars is it does, in fact, work. It just feels cheap in your hands. I thought I lost my old K400r, so I bought the new one and you can instantly tell the quality drop once you hold it. I tore my basement apart to find the old one because I'm not using this piece of trash! You can see the better K400rone in the second picture. Why make good quality items when you need to replace crappy stuff more often? Capitalism at its finest.

Simply put, they do what they are supposed to do. There are about seven PCs in my house including the bedroom and the living room. These keyboards are a godsend to my lifestyle

Plug and play. Used to control laptop that is wirelessly connected to TV from other room, about 15ft away. No issues. 2 finger drag to scroll, and tap to click on touch pad. All the features desired in small sturdy keyboard.

We have been very happy with the overall functionality of the keyboard and touchpad. It is a stand-in while we wait for a laptop repair, but has been a lifesaver during that time. The keyboard itself is responsive and the trackpad has worked well. The only "wish" I would have is that the batteries could last longer. Then again, it has seen some fairly heavy usage. As a bonus, it works with many smart TV's that have a USB port.

Perfect keyboard for any occasion. it works, wirelessly, love Logitech products, definitely pioneer in the industry. The buttons are not too click. It’s perfectly shaped and light.

Great compact keyboard, helps a lot with typing emails and passwords for my Xbox. I love this keyboard.

I personally use this keyboard for in office days! It’s perfect for loading up and taking into the office! It’s so compact but still works better than a laptop keyboard! I’ve had no issues with it!

Better than the original version. This is the keyboard I've been using since smart TVs were introduced and it's perfect for internet and work. I use with outlook 365 and word plus excel no problem.

I needed a keyboard as soon a possible and best but have me more than what i needed.

Fanstatic keyboard for livingroom media setup, lightweight and the trackpad work wonder!
